bus: brcmstb_gisb: register the fault code hook
Commit 44127b771d9c31 ("bus: add Broadcom GISB bus arbiter timeout/error handler") added everything that is required to register an ARM fault handler for imprecise external aborts, except that there is nothing calling this currently. We do not need to export that specific function and have to update arch/arm/mach-bcm/brcmstb.c to call it, simply, register the fault handler during the probe() function of the driver.
